TRICYCLE.

SPECIFICATION forming part 'of Letters Patent No. 322,406, dated July21, 1885.

Application filed February 5., 1885. (No model.)

To all whom it may concern: Be it known that I, D. MARSHALL BAB- COOK, aresident of the city and county of Worcester, State of Massachusetts,have invented certain new and useful Improvements in the construction ofTricycles, of which the following is a specification.

My invention relates more particularly to tricycles to be propelled byhand, though ap-,

plicable more or less to velocipedes and other vehicles. Its nature isfully shown in the following description of a tricycle embodying myinvention, as shown in the accompanying drawings.

In said drawings, Figure l is a side view. Fig. 2 is a plan, as seenfrom above. Figs. 3 and 4 are vertical cross sections of certain partsas seen from the right of Figs. 1 and 2, as hereinafter moreparticularly described. Fig. 5 is a perspective view of the seat, itsbrackets, and slide-bar G.

The same letters indicate the same parts wherever they occur.

A is the driving-wheel, supporting by its shaft or axle the frame B, andhaving a crank, b, at each end. The frame Bhas two stationarywell-braced uprights, O O, supporting the swinging frame D from theirupper ends,

the frame D having connecting ends E E to and supported from the trussedbar H, which also supports the ends of the splings K K, arranged toslide thereon. The brackets J J, under the seat,slide in the slottedends of the bar G, and their lower ends rest on the middle of thesprings K K, giving the required ease of motion. At L Lare the twosteeringwheels, pivoted to the fore part of the frame 13, and eachhaving a crank, l, with a pin fitting in the slotted end of the pivotedbar M, which has a connectingrod, N, to the steering-lever O, the endsliding in suitable notches in the frame B, and having compensatingcurves where it slides to compensate for the swing of the attachedlevers at each end, as shown at a a. At a is an automatic holderconsisting of a wedge, S, sliding in suitable ways on the bar below therod N, as shown in Fig. 3, one end of it being connected by chains overa pulley to the spring l?,by which allowing the rod to be moved by thesteeringlever O. The bar M is pivoted at its center to a stationarysupport on the front of the frame 13. l p

The construction of the wheels, frame,

braces, &c., not particularly specified, may

be of most any of the common forms in use.

adapted to the design and purpose of a mi cycle.

The operation is evident. The rider sitting on the seat, with the feetresting on the crossbar b of the frame, has most of the weight thrown onto the driving-wheel A, and is braced in the best position to exert allstrength of muscle in moving the frame D and propelling the vehicle,while the steering is readily controlled by hand and foot.

Having thus fully described my invention,

what I claim therein as new, and desire topatent, is-

1. 111 a tricycle, the combination of the frame, the driving-wheel, thetwo steeringwheels operated by cranks whose pins are acted on by apivoted slotted bar simultaneously in opposite directions, and themeans, substantially as described, for operating and holding the bar andwheels in position, as set forth.

2. The pivoted slotted bar arranged to move the two steering-wheelssimultaneously by moving the cranks in opposite direct-ions, incombination with the connecting-rod and steering-lever, substantially asspecified.

3. The double-curved connecting bar or rod, as and for the purposes setforth.

4. The automatically-locking holder consisting of the spring-operatedwedge S, wit-h the slide and frame embracing the rod N, in combinationwith the steering mechanism, as above set forth. 7

5. The springseat resting on brackets sliding in a bar of the frame andsupported on springs, in the manner and for the purposes above set forthand described.
